| Hi,
| `ipfw add 50 fwd,3128 tcp from any to any 80`  returns ipfw: 
| getsockopt(IP_FW_ADD): Invalid argument
| I'm running FreeBSD 4.6 with the default kernel. I guess 
| IPFIREWALL_FORWARD option is enabled in kernel.
| Do i need to enable it in /etc/rc.conf? if so then how?
| Thanks a lot.
| Regards,
| Rohit Neupane

options         IPFIREWALL              #firewall
options         IPFIREWALL_VERBOSE      #enable logging to syslogd(8)
options         IPFIREWALL_FORWARD      #enable transparent proxy support
options         IPFIREWALL_VERBOSE_LIMIT=100    #limit verbosity
options         IPFIREWALL_DEFAULT_TO_ACCEPT    #allow everything by default
options         IPV6FIREWALL            #firewall for IPv6
options         IPV6FIREWALL_VERBOSE
options         IPV6FIREWALL_VERBOSE_LIMIT=100

	Above are the relavent options required in kernel.

	Other option is

	# kldload ipfw

	and then test the ipfw rule.


Madness has no purpose.  Or reason.  
But it may have a goal.
